Application filed March 12, 1919. Serial are. aeaeei.

To (all who-"Lit may concern:

Be it known thatl, WILLIAM D. VRIGHT, acitizen of the United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have invented certain new and useful Improvements inAeroplanes, of which the following is a specification. c

My invention relates to a heavier than air flying machine in the form ofan aeroplane 'of the monoplane type and the objects of my invention arefirst, to provide a supporting plane that is so shaped and constructedand so positioned relatively to the propeller that the air bank is ofthe highest efficiency,

second, to provide an aeroplane of this type in which the plane is soshaped, braced and supported that the danger of collapse is reduced to aminimum, third, to provide an aeroplane of this type in which the aircurrent formed by the propeller is utilized to facilitate the support ofthe plane, fourth, to provide an aeroplane of this type which is narrowto facilitate landing .in narrow places such as a roadway, fifth, toprovide an aeroplane of this type which is so shaped, positioned andconstructed that there is little or no waste plane surface, sixth, toprovide an aeroplane of this type 3 with aileronsof twisted. doublecurved form and positioned on a double angle to the plane which performthe double function of stabilizing the plane and maintaining its ping inmaking short turns and seventh, to provide an aeroplane of this typewhich is simple, and economical of construction, du-

- rable, easy to operate, eflicient, easily controlled and which willnot readily dete- 40 riorate or get out of order.

With these and other objects in view as will appear hereinafter myinvention consists of certain novel features of construction,combination and arrangement of parts and portions as will be hereinafterdescribed in detail and particularly set forth in the appended claimsreference being had to the accompanying drawings and tothe characters ofreference thereon which form a part of this application in which i'Figure 1 is a top or plan view of my aeroplane complete.

Figure is a front view of one of the allerons minus the posts and guidewires and showing its relative position to this plane which is infragmentary section.

S 1m1lar characters of reference refer to sunllar parts and portionsthroughout the several Views of the drawings.

The main body portion 1, propeller 2, supporting wheels 3, supportingplane 4. allerpns 5, rudder 6, stabilizers 7, rear supporting plane 8,and stabilizing vertical plane 9 constitute the principal parts of myaer l'pl lnlang.d I

e 0 y 1, pro eller 2 su ortin wheels 3, rudder 6, sta bilizer 7 and Fearsup porfiing plane 8 are of the ordinary or conventional type, the plane4, however, is shaped as shown best in Fig. 1, provided with a pointedprojecting portion 4; which extends forwardly toin front of thepropeller andit is positioned asufficient distance above said propellerto permit the revolution of said propeller.

It is so positioned relatively to the body 1 that its rear end inclinestoward the body as shown best ;in Fig. 2 of the drawings. The rear endconsists of two V shaped members 43 which presents a fin surface to thea r when leaving the plane thus preventing a1r currents and eddiesfollowing the plane as in the conventional type. This plane is Slightlycurved on opposite sides so that the points 4 are the high points andthe plane recedes in every direction from these points 45. Secured tothe lower surface in the middle of this plane is a vertical plane 9which extends to the body 1 and tapering forwardly and backwardly asshown best in Fig. 2 of the drawings. This plane 9 serves as astationary stabilizer. Mounted below each. of the corners 4 are theailerons 5 mounted on supports 5 which provides an outward slant for theailerons 5. These ailerons 5 are constructed in twist/ed form as shownbest in Figures 2 and 3 so that they present a supporting surface to theair for side thrusts as well as maintaining the equilibrium of theplane. The plane 4; is provided with a net work of wires 4C forsupporting the plane and maintaining it in 1ts shape and it is connectedto and supported relatively to the body by means of the brace supports4'.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions, 1. do not Wish to be limited tothis particular construction, combination and arrangement but desire toinclude in the purview f my invention the construction, combination andarrangement substantially as set forth in the appended claims.

It is obvious that with this construction,

there is provided an aeroplane of the monoplane type in which the frontend of the plane extends in front of and abov e the propeller so thatthe upper surface of the plane is not subjected to an air current causedby the propeller nor is there an air pocket formed in front of the planeby the propeller but the front end of the plane is provided with anequal air bank which carries backwardly to the back of the plane and isnot.disturbed by the propeller or action of the propeller by formingpockets, that the full force of the air from the propeller is utilized,as a bank of air for the plane, that the plane is so shaped that amaximum of air bank is provided for the surface of the plane, that therear end of the plane is so shaped that the air currents and eddies donot follow the plane but. gradually taper out with the tapering pointsof the plane 4*, that the twisted and curved ailerons provide for thedouble function of maintaining the equilibrium of the plane as does thestraight ailerons and also provides a side surface for supporting theplane against side shifting in turning, that the stabilizing plane 9also reduces side shifting of the plane and forms a pocket for the airbank to assist in maintaining the equilibrium of the plane, that the airbank support divides and provides a main support from the point 4? tothe two points l where it leaves the plane.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A monoplane, including, a main body portion, a propeller mounted onthe front end thereof, a slightly tilted plane with its front endoverhanging said propeller and its rear end formed into two spaced apartpoints, and a stationary vertical V-shaped stabilizing plane extendingfrom said plane to the body.

2. A monoplane, including, a main body portion, a propeller mounted onthe front end thereof, a slightly tilted plane with its front endoverhanging said propeller and its rear end formed into two spaced apartpoints, a stationary V-shaped vertical stabilizin plane extending fromsaid plane to the body and a doubly twisted ailerons pivoted on an angleto said plane on oppositely disposed sides of said plane-spaced slightlyfrom said plane.

3. A monoplane including, an aeroplane body and a supporting plane, astationary vertical V-shaped stabilizing plan'e extending from saidplane to the body, and a doubly twisted aileron pivoted at an angletosaid supporting plane and at an angle to said stabilizing plane oneach side of said plane and spaced from said plane.

4 In an aeroplane of the class described, the combination with asupporting plane of a pair of ailerons, each mounted at opposite sidesof said plane at an angle to the transverse and horizontal axes of saidplane.

5. In an aeroplane of the class described, the combination with asupporting plane, of ailerons, each mounted entirely beneath theopposite sides of said plane so that the inner support is in advance ofthe outer support and at an angle t the transverse axis of itssupporting plane.

In testimon whereof, I have hereunto set my hand at an Diego, Californiathis 5th day of March 1919.

WILLIAM D. WRIGHT.
